This might be useful for folks delivering image-heavy apps on Mac OS X 10.6 and later...
Apparently with Snow Leopard, Apple has changed the default gamma of the system to 2.2 (used to be 1.8). <http://blogs.adobe.com/jnack/2009/09/why_your_web_content_will_look_darker. html> I was recently throwing some PNG images on a card on Rev that looked significantly darker than where they were created (in Photoshop), and for the life of me could not figure out why. I'm still searching for a reliable way to strip the gamma information from PNG images, but after finding the above article, I tried changing the screenGamma in Rev to 2.2 and amazingly (or maybe expectedly) the image seems to display properly. set the screenGamma to 2.2 I need to do some more testing, but it appears that when delivering apps on Snow Leopard that make heavy use of PNGs, one will need to do something to the effect of: if "mac" is in platform() and systemVersion() > 10.5 then ... Also used the following method to force refresh the display of the image: set text of img 1 to text of img 1 Hope this saves some head banging for other folks using images.
